Great video, David, and some of it I've been saying for half my life. Great economies tend not be great for the environment which - 'apparently' Trump is unaware of - was by definition pristine before humans evolved. Therefore, the pollution that we have to try accept is hardly normal. Pollution that came as a direct consequence of economic growth. Pollution that no sane person should want more of.

In a parallel universe, the world's political leaders will all have scientific backgrounds, no doubt. Just not this one, unfortunately. We seem to prefer buffoons and crooks to lead us.
